Webex Meetings VDI Release Notes

Audio and video for meetings requires significant bandwidth, and can cause a bottleneck going through the data center. Cisco Webex Meetings Virtual Desktop Software provides an enhanced experience in virtual desktop infrastructure (VDI) environments. The VDI software consists of the Webex Meetings app on the hosted virtual desktops (HVD) and the plugin on the thin clients. The software routes audio and video streams between the thin client and Webex Meetings cloud, without going through the HVD in the datacenter.

Virtual Desktop Infrastructure

With VDI, instead of a traditional desktop, you have a thin client and a hosted virtual desktop.

A thin client is a typically less costly and less powerful device than a desktop computer. Your organization may even use older, less powerful PCs as thin clients. Your hosted virtual desktop resides in a central server location called a data center. Your hosted virtual desktop includes your

  • Microsoft Windows desktop

  • Applications (such as Webex)

  • Data

Using your thin client, you access your hosted virtual desktop over a secure Citrix or VMware connection.

Webex works with VDI. However, sending the additional data that audio and video calls require, through the hosted virtual desktops, causes communications delays. This limitation is called the "hairpin" effect.

What's New 42.7

Quarterly release and N-7 support of VDI plugin

Meetings VDI updates now happen quarterly. Every four months there is a new update for the VDI plugin, which is aligned with slow channel (4x.2, 4x.6, 4x.10). Each plugin supports eight higher versions of the Meetings app. For example, 42.6 VDI plugin is compatible with 42.6-43.1 Meetings app.

Meanwhile, the VDI plugin is compatible with the previous slow channel version. For example, 42.10 VDI plugin also supports 42.6 Meetings app.

Webex Meeting VDI supports backward compatibility: the latest Webex VDI release supports the latest Webex VDI plugin as well as seven previous plugin releases (N-7).

 
If you are using a lower version of the plugin, but a higher version of the HVD, you will still get the feature list that is corresponding to the lower version of meeting client.

If Meeting Key Digits and End-to-End Encryption v2 (E2EE)) are both off, it is compatible with previous 41.2.x,41.3.x,41.4.x,41.5.2+. It won't be compatible with the version before 41.2. If anyone of the 2 features is ON, then it won't be compatible with previous 41.2.x,41.3.x,41.4.x,41.5.2+.
